Sending Math Notation Via EMails
Anyone who has sent mathematics notation via an email probably has experienced problems...if not at the ender's end, then probably at the receiver's end. And, the problem is not consistent (e.g. try sending the Word symbol for pi to yourself (in different fonts?)...does it get through?).
A useful resource is a special page on the website Karl's Calculus Tutor The full web site is a wellknown calculus resource operated by Karl Hahn, who I believe is an engineer living in Florida.
Start with his initial "Basic Guidelines," then peruse as needed:
 Raising Something to a Power
 Products
 Square Roots
 Using Parentheses
 Absolute Values
 Derivatives
 Limits, Summations, and Integrals
 Quotients and Division
 Subscripting
 Inequalities and Relational Symbols
 Infinity
 Greek Letters
 Vector Operators
 Special Functions
His suggested notation and approach are not standard, but they are a good step forward.
Also, while visiting the linked page, you should spend some time browsing the full Karl's Calculus Tutor website...especially if you teach (or are learning) calculus.
